Answer 3

1) 6*x = 9*4 + 2:

To solve this equation, we need to isolate the variable x. Let's break it down step by step:

First, let's simplify the right side of the equation: 9*4 + 2 = 36 + 2 = 38

Now, the equation becomes: 6*x = 38

To isolate x, we need to divide both sides of the equation by 6: (6*x)/6 = 38/6 x = 38/6 x = 19/3

So, the solution to the equation 6*x = 9*4 + 2 is x = 19/3.

2) y + 72 = 90 + 3:

Similarly, we need to isolate the variable y in this equation. Let's go step by step:

First, let's simplify the right side of the equation: 90 + 3 = 93

Now, the equation becomes: y + 72 = 93

To isolate y, we need to subtract 72 from both sides of the equation: (y + 72) - 72 = 93 - 72 y = 21

So, the solution to the equation y + 72 = 90 + 3 is y = 21.

3) 24 - x = 19:

Again, we need to isolate the variable x in this equation:

To do that, we need to subtract 19 from both sides of the equation: (24 - x) - 19 = 19 - 19 24 - x - 19 = 0 5 - x = 0

Now, to isolate x, we need to subtract 5 from both sides of the equation: (5 - x) - 5 = 0 - 5 5 - x - 5 = -5 -x = -5

Finally, to solve for x, we need to multiply both sides of the equation by -1: (-x) * (-1) = -5 * (-1) x = 5

So, the solution to the equation 24 - x = 19 is x = 5.
